I love your grandmother's recipe. In reading reviews, and being new at canning,(but not cooking)I used 8c pears,6c sugar and 2c brown sugar. I love the rich taste. The pectin came in 1.75z pkgs instead of 2z so I weighed out 2.25z.(x-tra pectin added because of reviews). Changed around some spices to my liking (1/4 tsp fresh ginger, 1 tbs cinnamon, 1 tsp allspice, 1/4 tsp grated nutmeg)and everything worked. Thank you for sharing this recipe, it is wonderful!
